Kodi 19.4 h265 hardware acceleration stopped after update



Hello, 
i have a raspberry pi 4 8GB with Bullseye and Kodi  19.4 installed.
This setup worked for years now and played even my h265 4K files perfectly via hardware acceleration.
Until recently when I made a sudo apt update && sudo apt full-upgrade

Since then kodi goes blank and restarts immedeately when trying to play a h265 (HD or 4K) with hardware acceleration on.
If I deactivate DRM hardware acceleration the files get played but the CPU maxes and the playback is choppy of course.

It seems like there where updates to libav (8.4.3.7)  from the bullseye repository.

sorry I am no expert, so please tell me what you need in order to fix this problem.

Thanks Michael
